PINPOINT TEST C: DTCs C1700, C1703 - PARKING AID SENSOR CIRCUIT FAILURE, B1299 - POWER SUPPLY SENSOR CIRCUIT SHORT TO GROUND

C1-C3:

C3-C4:

C5:

Normal Operation
The parking aid module supplies power to the parking aid ultrasonic sensors on circuit 7-GN1 (YE/RD). The parking aid module supplies ground to the parking aid ultrasonic sensors on circuit 9-GN1 (BN/RD). The parking aid module receives a signal from the parking aid sensors on circuits 8-GN19 (WH) and 8-GN20 (WH/RD).

Possible Causes
- circuit 7-GN1 (YE/RD) open or short to ground
- circuit 8-GN19 (WH) open or short to ground
- circuit 8-GN20 (WH/RD) open or short to ground
- circuit 9-GN1 (BN/RD) open
- parking aid sensor(s)
- parking aid module
